The short version

  • Each has a real cost: Packer packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence; Terraform hCL syntax requires learning a domain-specific language with limited GUI alternatives
  • They diverge on capability: Packer covers Image building, Terraform covers Infrastructure as code.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Packer

  • Packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • The Additional Use Grant forbids offering Packer to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Packer
  • Each version converts to the MPL 2.0 Change License only four years after that version is first published, and the Change Date is set separately per version
  • Alternative licensing for uses outside the grant must be arranged with the licensor rather than taken under the public licence

Terraform

  • HCL syntax requires learning a domain-specific language with limited GUI alternatives
  • State file management is complex, especially at scale with multiple workspaces
  • terraform import workflow is fiddly and must be done one resource at a time
  • No native error handling or try-catch capabilities like traditional programming languages
  • No automatic rollback capability - must manually delete and re-run if needed
